Whereas the CS01 is barely more than a synth-historical artefact, the CS33 builds on the concept and is quite a capable little synth even by today's standard. While it can do all sorts of bread and butter sounds, its signature sounds come from the PWM oscillator waveforms, twin linked filter modes and the built-in distortion effects.
